According to an arrest affidavit obtained by KDFW-TV (http://bit.ly/28NJVGk ) of Dallas-Fort Worth, Thedford said he dropped two other children off at day care about 9 a.m. Tuesday and had returned home to sleep. Only when he woke up three hours later did he find his youngest child stiff and "hot as a brick" in the minivan. He placed the child in the refrigerator with the door open before calling 911.

The National Weather Service says temperatures were in the low 90s but felt like the upper 90s.
